: Number 10 cotton duck, or #10 duck is not 10 ounce fabric, it is closer to 15
: ounce per square yard. #10 duck is a fairly stiff cloth with an
: abrasion-resistant weave, that is also fairly pucture resistant.

: Denim is a weave for clothing, so it is soft. Jeans have to bend, so you can
: get your legs in!

: You will have no trouble at all getting #10 duck from Seattle Fabrics by
: mail-order. See link below.

Andrew, or anyone else...

Do you know the relationship between the weight of the cloth and the number assigned to it? For example, what weight would, say, no. 9, or no. 11 be?

Thanks, Kelly
